Abstract

The invention discloses a spandex-containing polyester foam tackifying spun two-dimensional hollow fiber and a process, belongs to the technical field of chemical fibers, and solves the problems of poor water absorption, poor softness and weak rebound resilience of a composite fiber in the prior art, and the spandex-containing polyester foam tackifying spun two-dimensional hollow fiber comprises a moisture absorption melt prepared from spandex and a moisture absorbent, the moisture absorption melt and modified PET are subjected to composite spinning to obtain the finished product two-dimensional hollow fiber. Through the composite spinning assembly, the spandex melt and the modified PET melt are made into the hollow two-dimensional composite fiber, and the physical properties of high elasticity, high strength, wear resistance, corrosion resistance and the like of the composite fiber are improved; the moisture absorbent is added and matched with the fiber cavity, so that the requirements of the fiber for rapidly absorbing, diffusing and volatilizing moisture are met, the water absorption performance of the fiber is remarkably improved, the softness of the fiber is improved by using the flexible group, and the comfort degree of the fiber in contact with skin is improved; the whole process is simple, melt viscosity is tackified and homogenized, spandex is effectively utilized to keep elasticity, and the rebound resilience of the fiber is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of chemical fibers, and in particular relates to a two-dimensional hollow fiber and a process for viscosifying polyester foam containing spandex. Background technique [0002] With the rapid development of science and technology and the continuous improvement of people's living standards, people's requirements for the practical functions of clothing are not only to protect the body from the cold, but also in many ways: from comfort to health care, from safety to hygiene, from convenience for storage and It can be processed to suit different climates and environments, from adapting to the rhythm of life of modern people to adapting to the way of life of modern people. Especially in recent years, climate change is impermanent, and the daily difference of temperature is bigger, and people often because change clothes not in time, and cause the frequent outbreak of many diseases, this has just proposed higher re...
